Answer:
The loudness of sound is determined by<u> </u><u>Amplitude</u> of Vibration.
Explanation:
Louder Sound waves have higher amplitude(more energy and reach at far distances),Softer Sound have less amplitude.
Amplitude : The maximum disturbance of vibrating particle from their mean position.(/the height of peak)
The gravitational force between two objects is given by:
F = GMm/r²
F = force, G = gravitational constant, M and m are the masses, r = distance between the objects.
The force is dependent on only the masses of the objects and the distance between them. It is not dependent on the temperature of the objects.
Choice B
Here are the answers to the given questions above.
1. The reason why a person might want to wear snowshoes if walking a distance in deep snow is that s<span>nowshoes spread the person’s weight out, snowshoes reduce the amount of pressure on a given spot, and snowshoes keep the person from sinking in the snow. So the answer is all of these.
2. </span><span>The measure of the average kinetic energy of the particles of a substance is the TEMPERATURE.
3. </span>Archimedes’ Principle helps to explain the relationship between <span>buoyancy and density.
4. The one that is </span>equal to the buoyant force of a rock placed in a beaker of water is <span>weight of the displaced fluid.
Hope these answers help.</span>
Answer:
a) is the speed of each proton
b)
Explanation:
Given:
radius of path of motion,
we know charge on protons,
magnetic field strength,
we've mass of proton,
a)
From the equivalence of magnetic force and the centripetal force on the proton:
where:
v = speed of the proton
is the speed of each proton
b)
Now the centripetal force on each proton:
The position compared to that of home is a reference to displacement, I believe.
Displacement = x total - x initial
So I believe the answer is 5 blocks due north (if you’re walking linearly from your home), unless the questions is referring to relative displacement, in which then you’d need to use the Pythagorean theorem to find the hypotenuse between both positions. And then you’d have to find theta for the degrees between the south direction and the other unmentioned direction. But I don’t think that’s the case.
Distance refers to x total and doesn’t care for direction, as this refers to a scalar quantity opposed to a vector. Thus the equation is just
d = x
So 8 blocks + 3 blocks = a distance of eleven blocks walked total
